If the elco Burner starts briefly, then switches off and the red indicator light comes on, it is possible that the control unit has been manually locked. In this case, unlock the unit.
Why elco VG4.610 DP Burner does not start?
If the elco Burner does not start, it could be due to the air pressure switch not being in the rest position, being incorrectly adjusted, or having a contact welded. To resolve this, readjust the pressure switch, check the wiring, and replace the pressure switch if necessary.
What to do if elco VG4.610 DP does not start, even with normal gas pressure?
If the elco Burner does not start despite normal gas pressure, it may be due to insufficient gas pressure or a wrongly set/defective gas pressure switch. Check the gas lines and clean the filter. Also, inspect the gas pressure switch, and replace the compact gas unit if required.
What to do if elco VG4.610 DP Burner switches off during operation?
If the elco Burner switches off during operation, it could be due to the air pressure switch contact opening during start-up or operation, or flame failure during operation. Adjust or replace the pressure switch. Check the ionization probe circuit. Check or replace the control and safety unit.
What to do if elco VG4.610 DP blower starts but the burner doesn't?
If the elco Burner blower starts up but the burner does not, it could be because the air pressure switch contact does not close. To fix this, readjust the pressure switch, check the wiring, and replace the pressure switch if needed.
What to do if elco VG4.610 DP Burner blower starts but the burner doesn't, and there is flaring?
If the elco Burner blower starts up but the burner doesn't, and there is flaring during pre-ventilation or pre-ignition, check the valve and flame monitoring system.
Why elco VG4.610 DP does not start after thermostatic closure?
If the elco Burner does not start after thermostatic closure and there's no malfunction indicated on the control and safety unit, it could be due to a drop in supply voltage or a power failure. Check the cause of the voltage drop or power failure. If necessary, replace the control unit.
What causes a servomotor fault in elco VG4.610 DP?
A servomotor fault in the elco Burner can be caused by clogging or locking of the air flap, or an internal fault with the servomotor. Replace the servomotor to resolve this issue.
What to do if there is no heat requested from elco Burner?
If there is no heat requested from the elco Burner, it could be due to defective or incorrectly adjusted thermostats. Adjust the thermostats, and replace them if necessary.
